example 1

[0036]This example illustrates the use of a gum as a binder during extrusion of an animal feed having less than 4 weight percent starch. 5ZF1 Mazuri Wild Herbivore Diet Hi-Fiber meal (PMI Nutritional International, LLC of Brentwood, Mo.) having less than 4 weight percent starch was homogeneously mixed with approximately 5%, 3% and then 1% of a heat-settable gum in the form of Ticagel PF-80 (TIC gums, Inc. of Belcamp, Md.). 5ZF1 Mazuri Wild Herbivore Hi-Fiber has the following ingredients:

In the three runs, Ticagel PF-80 a pet food-grade kappa-carrageenan that forms a gel, was used. The dry mixture was homogeneously mixed and then ground in a Fitzmill® Grinder (The Fitzpatrick Company of Elmhurst, Ill.) through a 4 / 64 inch ...

[0040]5ZF1 Mazuri Wild Herbivore Diet Hi-Fiber meal (PMI International, LLC of Brentwood, Mo.) was mixed with approximately 10% of Ticagel 550 PT in a first run and 10% Guar 8 / 24 in a second run. (Both from TIC gums, Inc. of Belcamp, Md.). 5ZF1 contains less than 4 weight percent starch Both mixtures were homogeneously mixed and then ground in a Fitzmill® Grinder (The Fitzpatrick Company of Elmhurst, Ill.) passing through a 4 / 64 inch screen.

[0041]After grinding, the dry mixture was introduced into the extruder using the extruder setup as described in Example #2.

[0042]The ground dry mixture was mixed with water added at a rate of 0.43 lbs per minute at the conditioning section of the extruder. The addition of steam to the dry mixture formed a mash that had a temperature of about 208° F.

[0043]Additional water was added to the inlet of the barrel at the rate of 1.07 lbs / min. The screw was operated at a speed of about 515 RPM. The hot mash was cooked and sheared until the hot mash forme...

example 3

[0045]Different levels of a kappa-carrageenan gum (Ticagel PF-80) were tested as a binder with 5MG7 Wild Herbivore Diet (from PMI International, LLC of Brentwood, Mo.). 5MG7 Wild Herbivore Diet has the following ingredients:

The 5MG7 Wild Herbivore Diet was extruded (Wenger X-200, Wenger Manufacturing Co, Sabetha, Kan.) without a binder and produced particles that would not hold together.

Abstract

The present invention includes methods for producing an extruded food particle by extruding through an extruder having a screw within a barrel, a composition containing nutritional food components, essentially no starch and a gum in an amount sufficient to act as a binder once the composition exits the extruder. The present invention also includes extruded food particles that do not use starch as a binder.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]None.BACKGROUND OF THE INVENTION[0002]The present invention generally relates to extrusion of feed and food products. More specifically, the present invention relates to methods of extruding feed and food products that uses a heat-set gum rather than starch as a binder during extrusion. The present invention also includes extruded feed and food products that contain a heat-set gum as the binder and little, if any starch.[0003]Extrusion cooking devices have long been used in the manufacture of a wide variety of edible and other products such as human food and animal feeds. For example, large extruders have been used for many years for the production of dry chunk-type dog foods. Generally speaking, such equipment includes an extruder having an elongated, tubular barrel with one or two elongated, helically flighted, axially rotatable screws therein. A multiple-orifice die is normally attached to the outlet end of the extruder barrel and is th...
